TO ALL WHOM IT MAY CONGERN:

Be it known that I, CHARLES G. Warennunr, of New York, in the county ofNew York, and State ot' New York, have invented a new and usefulimprovement in Wooden Pavementst; and I do hereby declare that thefollowing is aV full, clear, and exact description thereof, referencebeing hadV to the accompanying drawings, in whicl1-.

Figure 1 is a plan view of a section of' a pavement constructed 1naccordance with my invention.

Figure 2 is a plan view ot' one ot' the blocks composing the pavement,and

Figure 3 is an end view of the same. i

Figure 4 is a bottom view of the pavement.

Figure 5, a side elevation of the same, and

Figure 6 an end view.

Figure 7 is a top view of one ol' the movable strips.-

Similar letters of reference indicate like parts in all the figures.

My invention relates to that class of pavements known as'woodenpavements, and it consists in so arranging and fastening the same fromthe top that each block'of which it is composed has a bearing upon itsadjoining six by means of movable strips horizontally laid in after theblocks have been placed upon their hed, and so fastened down by bolts ortheir equivalents, and which may be withdrawn, so that one or moreblocks may be taken up for the purpose of repairing vater-mains, sewers,or gas pipes, and the same be replaced again with case ondfacility, andwith all its former strength and bearings.

To enable others to make and use my invention, I will now proceed todescribe the same by reference to the accompanying drawings.

A are the wooden blocks, having two projections on each side, extendingabout half way up the blocks A. These projections vary in size, thelarger ones being twice as long as the others, and are placed on opposite sides and opposite ends ol` the block, as seen in ligs. 2 and l, sothat, when the pavement is laid, the blocks will fit into one another,and each have a bearing on and be'supported by six adjoining ones. C areremovable strips, which rest upon the part of the projections Il, andarc'held firmly down -upon said projections by means of bolts or spikesD driven into the sides of the blocks A. These strips are of about thesame length as the blocks, and are mitred at each end for the purpose ofinsuring a. perfect tit, as seen in iig. 7. One end of each of theblocks A is cnt away, forming a projection, E, as seen in-figs. 2 and3,whichprojections are flush with the upper surfaces oi' strips C, sothat, when'the pavement is laid, there will be an opening between theends of the b ocks for the purpose of driving in the bolts. l i

The mode of laying the pavement is as follows: 'ihe'road-bed havingrbeeuconcreted with suitable material, thcblocksare placed thereon and fittedinto each other, as seen in tig. 4, each block resting against and beingsupported by six adjoining ones. The desired distance or number ofblocks being thus laid, the strips C are inserted in the spaces betweenthe blocks, formed by the-projections B, and the bolts D driven into theblocks,

- in the manner shown in iig. l, holding lall the blocks firmlytogether, and rendering it impossible to remove any of them withoutfirst withdrawing the bolts D and removing the strips C. The spaces Cbetween the blocks muy afterwards be filled up with tar, pitch, gravel,or'other suitable substances. l

If it is desired to remove any portion of the pavement for the purposeof repairing sewers or watermains, or for any other purpose, the tar orpitch filling is dug out, and the bolts or spikes D withdrawn by-anysuitable instrument, and the strips C rcmoved,`wlien the blocks may beeasily taken out. They are afterwards replaced, as above set forth, andwill possess all their former strength and bearing. For permanentpavements the strips C maybe of any length convenient, they being madein sections only for the purpose of facilitating thework of taking upand relaying. l

By melting the projections B rise llush with the end projections E thestrips C may be dispensed with, in which case the bolts D will be drivenin immediately above the shoulders formed by projections B, and beardirectly upon them, in like manner as they bear upon the strips C whenthe latter are used.

Having thus fully described my invention, and the manner in which thesame is or may be carried into e'il'ect, what l clojm as my invention,and desire to secure by Letters Patent, is

1. The blocks A, wit-l1 their projections B :und E, constructed andarranged substantially as and for the purpose set forth.

2. In combination with the blocks A, lmvirg projections 15 and E, Icla-im thc movable strips C :unl bolts D, substantially as and for thepurpose set forth. i

3. In combination with the blocks A, lmying projections B and E, I claimtllfc bolts D, with or without thc strips C, substantially :1s andfor-the purpose described.
